直肠癌术后局部复发危险因素临床病理研究

目的 探讨直肠癌根治性切除术后局部复发的危险因素.方法 回顾性分析2000年1月至2005年12月该院收治的行直肠系膜全切除(TME)的直肠癌69例临床资料,采用病理大切片技术检测直肠系膜转移及环周切缘情况.分析局部复发与临床病理的关系.结果 直肠癌根治性切除术后局部复发率为11.6%(8/69).局部复发与肿瘤直径(P=0.011)、浸润深度(P=0.021)、分化程度(P=0.001)、癌性穿孔(P=0.013)、淋巴结转移(P=0.041)、脉管侵袭(P=0.014)、环周切缘情况(P=0.005)和Dukes分期(P=0.018)密相关,与病人性别、年龄、肿瘤部位、系膜转移和手术方式不相关(P>o.05).结论 肿瘤直径、浸润深度、分化程度、癌性穿孔、淋巴结转移、脉管侵袭、环周切缘情况和Dukes分期是直肠癌根治性切除术后局部复发的重要因素.

Risk factors of local recurrence after curative resection in patients with rectal carcinoma

[Objective] To investigate the risk factors of local recurrence after curative resection in patients with rectal carcinoma. [Methods] Cancer specimens from 69 patients with rectal carcinoma who received total mesorectal excision. The relationship between mesorectal metastasis/circumferential resectionmargin status and local recurrence was identified. The relationship between local recurrence and clinicopathologic characteristics of rectal carcinoma was evaluated.[Results] Local recurrence after curative res...
